Product Description Unlock endless possibilities in IoT, prototyping, and embedded projects with the Lonely Binary ESP32-C3 OLED Kit. This comprehensive bundle includes three high-performance ESP32-C3 development boards, each featuring a built-in OLED display for real-time data visualization and debugging. Paired with versatile expansion shields, this kit supports seamless integration of protected LiPo batteries (like 18650 cells) for portable, battery-powered applications. (Battery is not included.)
Designed for uninterrupted operation, the LiPo battery functions like a UPS system: when Type-C is connected, the ESP32 draws power from it and charges the battery; if disconnected, the battery instantly takes over without rebooting or interrupting your code.
The included shields provide flexible connectivity options:
2.54mm Expansion Shield with dual male/female GPIO pins to eliminate jumper cable mismatches
Screw Terminal Shield ideal for secure, permanent installations
Non-Screw Terminal Shield perfect for quick prototyping with raw cables
All shields feature intelligent power management—stepping down battery voltage to a stable 3.3V for the ESP32-C3 while enabling simultaneous charging via USB Type-C. Plus, built-in battery monitor pads allow easy voltage monitoring by simply shorting them, ensuring you always know your power status.
Compatible with Arduino IDE, C++, MicroPython, ESP-IDF, and more, this kit is designed for makers, hobbyists, and professionals building smart devices, sensors, or wearables. Whether you're creating a wireless display, battery-powered gadget, or custom prototype, the Lonely Binary ESP32-C3 OLED Kit delivers reliability, versatility, and ease of use in one affordable package.
Bullet PointsTriple ESP32-C3 Boards with OLED Displays: Includes 3x compact ESP32-C3 development boards equipped with integrated OLED screens for instant data readout, Wi-Fi/Bluetooth LE connectivity —perfect for IoT prototyping and real-time monitoring.
Lipo UPS Power Management: LiPo batteries (not included) act as an instant backup; Type-C powers the board and charges the battery when connected, switching to battery power without reboots or interruptions for continuous operation.
Versatile Expansion Shields: Comes with a 2.54mm Expansion Shield featuring dual male/female GPIO pins to avoid jumper cable issues, a Screw Terminal Shield for durable permanent projects, and a Non-Screw Terminal Shield for fast prototyping with direct raw cable connections.
Universal LiPo Battery Compatibility: All shields support any protected LiPo battery (e.g., 18650), with automatic 3.3V step-down for powering the ESP32-C3 and built-in charging via USB Type-C for uninterrupted operation.
Battery Monitoring Made Simple: Integrated battery monitor pads on every shield—short them to enable real-time voltage tracking on your ESP32-C3, helping you manage power efficiently in portable setups.
Ideal for Makers and Developers: Supports frameworks like Arduino, MicroPython, and ESP-IDF; great for wireless sensors, smart displays, or custom electronics—affordable, expandable, and user-friendly for beginners to experts.
